A
Attract each other
a (a) Although moving beams of protons are like currents and two parallel currents should attract each other. But the electrostatic force will dominate over the magnetic force and hence they will repel each other.

A galvanometer is used in laboratory for the null point in electrical experiments. If, on passing a current of $6 \,m A$ it produces a deflection of $2^{\circ},$ its figure of merit is close to :
For a solenoid keeping the turn density constant its length is halved and its cross section radius is doubled then the inductance of the solenoid increased by.....$\%$
On connecting a battery to the two corners of a diagonal of a square conductor frame of side $a$ the magnitude of the magnetic field at the centre will be
$A$ particle having charge $q$ enters a region of uniform magnetic field $\vec B$ (directed inwards) and is deflected a distance $x$ after travelling a distance $y$. The magnitude of the momentum of the particle is:
In figure the cube is of $40\,\, cm$ edge. Four straight segment of wire $ab, bc, cd$ and $da$ form a closed loop that carries a current $I = 5\,A$. A uniform magnetic field $0.02\,\,T$ is in $+y\,-$ direction ratio of magnetic force on segement $ab$ and $bc$ is
The region between $y = 0$ and $y = d$ contains a magnetic field $\vec B = B\hat z$ A particle of mass $m$ and charge $q$ enters the region with a velocity $\vec v = v\hat i$. If $d = \frac{{mv}}{{2qB}}$ , the acceleration of the charged particle at the point of its emergence at the other side is
A solenoid is oriented end-on so that its opening is perpendicular to the circuit containing the two light bulbs as drawn in figure $C_1.$ For figure $C_2$ and $C_3,$ a shorting wire of negligible resistance is added as shown. Assume that the magnetic field from the solenoid, shown coming out of the plane of the page, decreases uniformly with time at the same rate for each circuit. Rank the circuits for the brightness of the bulb labeled $R_1$ from brightest to dimmest.
A moving coil galvanometer has $N$ number of turns in a coil of effective area $A$, it carries a current $I$. The magnetic field $B$ is radial. The torque acting on the coil is
